Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, and in particular relates to a connection mechanism for photovoltaic support columns and inclined beams. Background Technology

[0002] Currently, most of the profiles used to assemble photovoltaic (PV) brackets are U-shaped steel structures. The mounting ports are arranged linearly on the profiles and can be used with triangular connectors for PV bracket assembly. Compared with U-shaped steel structures, using round tube profiles as columns can improve the stability and strength of PV brackets. Now, triangular connectors can be set at the connection points between the columns and the inclined beams to achieve the connection between the two.

[0003] When assembling photovoltaic (PV) brackets, it is necessary to ensure the inclination and height of the inclined beams and to ensure that the inclined beams of the array of PV brackets are on the same inclined plane. Therefore, it is necessary to adjust the height of the front and rear columns. The current method of installing the columns is to pre-position the lower cylinder by installing concrete, then insert the cylindrical column into the lower cylinder, and arrange multiple fastening screws on the periphery of the lower cylinder. After the height adjustment is completed, the pressure provided by the fastening screws is used to pre-fix the column. Then, the drilling mechanism is used to open holes online and install bolts for permanent fixation. The installation method is relatively complicated and affects the assembly efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a connection mechanism for photovoltaic support columns and inclined beams. Through the design of the new connection mechanism, there is no need to pre-set the lower cylinder and the upper pre-tightening screws, and the column can be directly installed and positioned. Through the design of the fastening bolts and the waist-shaped hole, the lower support can be limited to vertical adjustment. Through the design of the adjusting bolt, the contact point between the lower support and the tapered rod section can be switched by adjusting the screwing length, thereby adjusting the height of the upper support. The height of the column can be indirectly adjusted, which facilitates the operation of the staff and improves the assembly efficiency and accuracy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a connection mechanism for photovoltaic support columns and inclined beams, including adjusting bolts, a lower support for connecting the column and an upper support for connecting the inclined beam;

[0007] The column is a circular tube structure, and the inclined beam is a U-shaped steel.

[0008] The lower support includes a lower end tube, the bottom end of which is provided with a tapered end, the width of which decreases from bottom to top. The upper support is a triangular connector, and the upper support is rotatably connected to the top end of the lower end tube by a pin.

[0009] The lower end tube is provided with a connection port, the top of the column is provided with a waist-shaped opening parallel to the axis, the bottom gap of the lower end tube is provided inside the top of the column, and a fastening bolt is provided between the connection port of the lower end tube and the waist-shaped opening of the column.

[0010] The adjusting bolt includes a threaded section and a washer;

[0011] One end of the threaded section is sequentially connected to a tapered section, a cylindrical section, and a screw head. The outer diameter of the tapered section increases sequentially from the threaded section to the cylindrical section. A nut is connected to the external thread of the threaded section.

[0012] The gasket is a T-shaped sleeve, and the end face of the large-diameter section of the gasket near the small-diameter section is provided with an arc-shaped surface that matches the circumferential side of the column.

[0013] The top of the column is provided with a through-hole in the area below the waist-shaped opening. The gasket is fixed to the periphery of the column by welding. The arc-shaped surface is in contact with the outer surface of the column. The gap of the small-diameter section of the gasket is set in the through-hole on one side of the column.

[0014] The cylindrical section is inserted through the through-hole on the other side of the column, the threaded section passes through the washer, and the nut is welded and fixed to the outer end face of the washer.

[0015] Furthermore, one end of the nut is provided with an end piece, and several notches are provided at the edge of the end piece, and the welding points of the nut and the washer are located in the notches.

[0016] Furthermore, the cylindrical segment and the conical segment have the same length, and the length of the conical segment is the same as the radius of the inner cavity of the column.

[0017] Furthermore, the outer diameter of the bolt segment of the fastening bolt is consistent with the width of the waist-shaped opening and the inner diameter of the connection opening, and the bolt segment of the fastening bolt slides up and down along the waist-shaped opening.

[0018] Furthermore, the upper support includes a top plate, both ends of which are provided with mounting openings, and the bottom surface of the top plate is provided with lug plates connected to the pin shaft at the center of both sides.

[0019] Furthermore, the outer diameter of the lower end tube is consistent with the inner diameter of the column.

[0021] 1. This utility model, through the design of a novel connecting mechanism, eliminates the need for pre-setting the lower cylinder and the upper pre-tightening screws, allowing direct installation and positioning of the column. The design of the fastening bolts and the oblong hole restricts the lower support to be adjustable only vertically. The design of the adjusting bolts allows for switching the contact point between the lower support and the cone section by adjusting the screwing length, thereby adjusting the height of the upper support and indirectly adjusting the height of the column. This facilitates operation by workers and improves assembly efficiency and accuracy.

[0022] 2. The lower support of this utility model is supported by adjusting bolts, and tightening the fastening bolts can stabilize the support connection point, improving the connection strength and stability between the inclined beam and the column. Similarly, the nuts and washers are fixed by welding, and the washers and columns are fixed by welding, which can achieve permanent fixation.
